METALLIC VEIIICLE-WHEEL.

To @ZZ whom t may concern:

Be it known that I, Annan L. PnrnAM, a citizen of the United States of America, residing at Detroit,l in the county of Wayne and State of Michigan, have invented certain new and useful 'Improvements in Meof which the following is a specification, reference being had therein to the accompanying drawings.'

The invention relates to metallic vehicle wheels and more particularly to that type known as twin wheels.

It is the object of the invention to obtain a construction .employing pressed ysheet metal spiders and channel-section runs, the construction being one which permits of readily assembling and securing the pants.

In the drawings: Figure 1 ,1s a sectlonal side elevation of the wheel; Fig. 2 is a crps's section thereof; Fig. 3 isa section on line en Fig. 4; isa modified construction as applied to a single wheel; and F1g.-5 1s a cross-section thereof. i

A is the spider section, which is formed of complementary pressed sheet metal sections, together constituting a series of radially-extending tubular spokes unitedby a common hollow center. l.

B is a metallic rim,'having inwardly-extending fianges U on opposite sides thereof forming a channel cross section.

To secure the spider within the rim it is necessary that the spokes should extend radially to the peripheral portion of the rim,

but the inwardly-extending flanges,if integrally formed, would prevent the assembling of the parts.

feet of the flange itis should be'integral with that portion ofthe rim to which the endsof the spokes are secured. I have therefore formed the rim.B of two complementary sections abutting against each other in the central plane of the wheel. rThis, in 'case of a twin wheel construction, permits of slipping the periphei al portion of the rim over the ends of the spokes et' cach spider section without interference from the flange which is on the outside of the rim. The spokes and rim are inter-locked bv fittings D, preferably forg ings, which have socket portions E for engaging the ends of the spokes, and segmental i'iange portions F for litting within the Laterally-extending lugs G on these Specification of Lettere Patent.

fittings engaging apertures H in the flanges C, and outwardly-extending lugs I engaging apertures in the rim B, will serve to interlock against relative movement under the torque of the wheel. I

The inner ends of the spiders A are clamped to a common hub J, while at their outer ends the spiders and rim sections are .clamped together by bolts K, preferably passing through alined apertures in the fittings D and the flanges C. Thus whenl the parts are assembled, the twin sections of the wheel are interlocked With-each other, and with their respective spiders, while the inwardly-extendingflanges C on both sides of the wheel form a strong reinforcement for the rim.

In the modiiied construction shown in Fig. e a single wheel, instead of a twin wheel, is formed, the rim being split in the central plane of the spokes, and the two sections being interlocked with the spider by fittings L and clamping bolts M.

1. A metallic vehicle wheel, comprising a spider section, a rim section of channel cross section -having inwardly-extending flanges uponthe opposite'sides thereof, and a peripheral portion for fitting over the ends of the spokes of the spider, said rim being divided for assembling on said spider, and fittings for interlocking said spokes with said -rim sections laterally engageable therewith.

2. A metallic vehicle wheel, comprising a spider section having radially.- extending spokes and a rim of channelcross section having inwardly-extending flanges on opposite sides thereof and a'peripheral portion forfltting about said spokes, said rim being divided centrally of the peripheral portion thereof to permit of engaging said spider from opposite sides, and socket fittings engaging the spokes of' said spider having lugs interlocking with apertures in said rim and laterally engageable therewith.

3. A metallic vehicle wheel, comprising a spider section having radial spokes, and a 4 rim of channel cross' section ,havinghin wa-rdly-.eXtending flanges and a'peripheral portion for fitting about the spokes :of the spider, said rim being said spider from opposite sides thereof, and socket fittings for engagement with the ends divided centrally of v the peripheral portion for engagement with of the spokes and fitting within the periph eral portion of said rim, said fittings having laterally-extending lugs for engaging apertures in the inwardlyeextending flanges of the rim7 and outwardly-extending lugs for engaging notches in the peripheral portion of the rirn, and clamping bolts tor securing said rim sections and fittings to said spider.

(L A metallic vehicle wheel, Comprising a spider section having `radially-extending spokes, a rim of channel'eross section having'inWardly-extending flanges on the opposite sides of said spider and a peripheral portion for fitting over the ends of/said spokes, said rixn being divided centrally of the peripheral portion 'for-engagement from opposite sidesof said spider, socket fittings for engaging the ends of the spokes fitting within the peripheral portion of said rim and having laterally-extending ings for en gaging apertures in said inwardly-extending iianges, and outwardly-extending lugs for engaging notches in said peripheral portions, and clamping bolts passing through said inwardly-extending fianges and registering apertures in said fittings.

5. A twin metaliic vehicle wheel, comprising twin spider sections havingradiallyextending spokes, twin rim sections each havinga peripheral portion for fitting about said spokes and an -inwardlywextending flange portion, socket fittings engaging the ends of said spokes having 'laterally-extending lugs engaging apertures in said inva'ardlyextending rim, and outwardly-extending lugs engaging notches inthe pei'ipherai portion of said rim, a common hub for uniting said spider sections, and clamping bolts for securing said rim sections to each other.
